Personally, I think that the combination of the following two books are your best bet for getting a handle on Arabic verbs:

1) Fundamentals of Classical Arabic Volume 1
2) "All the Arabic you never learned the First Time Around"

If you go through the material related to verbs in both books, honestly, you should have covered 95% of all you would ever need to know to recognize and conjugate Arabic verbs (though that's not to say that you've mastered Sarf). So for purposes of being able to read, understand, identify, and use Arabic verbs, you should be set. If you need additional references, the material on "www.learnarabiconline.com" and in the book "From the Treasures of Arabic Morphology", in that order, are helpful.
